Abstract

"PROCESSO E DISPOSITIVO PARA A MEDIçãO DA CURVA DE RESFRIAMENTO DE MASSAS FUNDIDAS". A presente invenção refere-se a um processo para a medição da curva de resfriamento de massas fundidas e/ou da curva de aquecimento de corpos de prova de massa fundida, com uma fibra óptica, sendo que uma extremidade de imersão da fibra óptica que apresenta uma superfície livre, pelo menos, parcialmente é circundada distanciada por uma câmara de recepção de corpo de prova resistente à temperatura, de tal modo que a fibra óptica mergulha com sua extremidade de imersão na massa fundida, e nesse caso, é formado um corpo de prova na câmara de recepção de corpo de prova, sendo que depois a câmara de recepção de corpo de prova com o corpo de prova e a fibra óptica é extraída da massa fundida de metal, e a curva de resfriamento do corpo de prova e/ou, após o endurecimento precedente do corpo de prova, o decurso da temperatura durante o aquecimento, é medida com auxílio de um sinal recebido pela fibra óptica e transmitido a um aparelho de medição. Além disso, a invenção se refere a um dispositivo correspondente, bem como, a seu emprego.
